TerraFirma Foundation Systems
TerraFirma Foundation Systems
Thousands of NW homeowners have trusted TerraFirma Foundation Systems to keep their homes safe, dry and stable since 2005. Nearly half of our business comes from referrals or repeat customers. We can help you too! TerraFirma is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

Bellos Construction
Bellos Construction
We pride our company on reliability, great communication, integrity, and quality work. We have 15 years of experience in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!
"We actually had Bellos Construction do considerably more than just a bathroom remodel. Additional work included installing flooring, installing insulation and drywall, demolition work, roofing repair, etc. Overall the experience was good. Jose is very responsive and helped me out quite a bit dealing with renovating and repairing an older house that was not properly taken care of by the previous owners/renters. The only real issue we had was confirming the materials that would be installed in the bathroom (i.e., fixtures, etc). There was some miscommunication there that probably was not helped by the fact we are out of state and trying to manage a construction project. One thing that stood out about Jose was his willingness to help out with things that didn't fall under his contractual obligations. For example, he helped me transport a water tank when he didn't need to do so. If we have a need for services that Bellos Construction offers, then we will definitely consider them in the future given our experiences with them."

1-800 Water Damage
1-800 Water Damage
1-800 Water Damage Portland and Vancouver has more than a decade of experience in providing first-rate restoration services for all problems related to water, fire, sewage, and mold damage. Our technicians are all IICRC and Lead certified, which means that they are able to handle any size restoration job for both residential and commercial applications.
"WARNING!!They will take advantage of you. Save thousands by calling SERVPRO or any other reputable company! I am a business owner with multiple locations. We have always used Servpro when we have had a broken pipe, damaged sprinkler head or septic issue. In the last incident, family friends, who own a local septic clog removal service suggested using 1-800-water damage instead of Servpro, as they heard they were cheaper. The manager did call them. I was shocked at the people who arrived. The appearance of the people was unprofessional to say the least. Next they cam in and asked why are we here as there is no water. I explained the employees had cleaned the water from the broken sprinkler head, and that our concern was with the insulation in the attic around the pipe where we could not get to. They stated they had to get someone to asbestos test the insulation and that would rush that. They then started walking around stating they may need to pull up our WATERPROOF luxury vinyl flooring we had installed only 5 years ago!! I said absolutely not and asked why would you even think that and they said well it could damage the floor under…. Our floors are cement slab and the vinyl was commercial and professionally installed. The water had only come from the pipe for roughly 5 mins before the water was shut off. I knew then that these guys either didn’t know what they were doing, or more likely were looking to make the most money they could off each job regardless of the need. They then walked around chatting finally took some hand held moisture testers which they mostly used while walking not on any of they walls. They ended up leaving many dehumidifiers for a building that had a small amount of water in the front part of the entry only. Three days later they call saying that they have to put multiple holes in our interior walls and pump on air to dry out they walls!!! I asked them why and they said they had detected moisture. I asked them in which walls of our over 6000 sq ft building as none of the walls were wet and they had commercial base on the bottom so only minimal if any water could have gotten at the very bottom only before it was cleaned up. He answer “umm well… all of them” he wanted the punch multiple holes in each wall throughout my building! I said he was being insane. That the water didn’t hit 3/4 of the building. I told him I wanted to see moisture readings from the walls in the back and he said well…. “It’s more that we detected moisture in the hall entryway …. Not on the walls themselves”. I told him that if he where to do this we would have to shut our business down because every room would have big machines. We likely would loose multiple clients and potentially tens of thousands of dollars and then we would have to pay to repair the walls on top of that. There was no way for a small and brief water damage to have caused this devastating result when the floors hadn’t even been exposed to water for most of the building. They had never even tried to take sample or remove the wet insulation which was our only real concern. Finally I told them I was going to call Servpro for a second opinion and this young man then said that it wasn’t up to me! That the building owner had signed off ….. A COMPLETE LIE… I called SERVPRO, who came out stated first, the building had no need for that much dehumidifier. Second that simply removing a small bit of the rubber base cove in the entrance would allow the air to dry the very minimal amount of water on the very edge of the Sheetrock behind the base cove. Additionally, they said that as interior walls that have no insulation in them, that there was no need to put holes in any walls as the water would not accumulate there without insulation to hold it. They said it was clear this company 1-800 was trying to get tens of thousands of dollars from us when it was completely unnecessary. The worst part is they knew we would loose customers possibly have to permanently shut down and had no care they just think oh well that is what insurance is for!"

FAQs for basement waterproofing projects in Kelso, WA
Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
